- Only reset the oil change disp lay w hen
you have completed an o il change .
- Maintain ing the service intervals is of vi­
ta l importance for the life and value of
you r vehicle espec ially the engine . Serv­
ice interva ls shou ld not be exceeded,
even by a short distance .
- If the vehicle battery is disconnected,
the timing for the next oil change wi ll be
i nterrupted.
If the vehicle is stationary
for a long time, have all scheduled serv­
ices performed.
- Even if the mileage driven is low, the
maximum period of one year from one
service to the next must not be exceed­
ed.

188 Smart Technology
by pressing firmly on the brake pedal. Avoid
heavy braking during the break-in period.
Wear Brake pad
wear is largely dependent on the
way the vehicle is driven and on operating
conditions. This is especially true if you are
driving frequently in the city and on curves or
with a sporty driving style.
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight
condensation or after washing your car, the
braking effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be "dried" first with a few careful
brake applications.
At higher speeds and with the windshield wip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This action which is not felt by the driver hap­
pens at regular intervals and facilitates a bet­
ter reaction time for the brakes in wet weath­
er.
The braking effect can also be reduced if you
are driving on salted roads and you do not ap­ ply the brakes for long periods of time. The
layer of salt on the brake rotors and pads
must be worn off first when the brakes are ap­
plied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake ro ­
tors and dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
high speeds is recommended to clean the
brake rotors and pads
Q &. .
Brake system malfunction
if you notice that the brake pedal travel has
suddenly gotten larger, then a brake circuit
may have failed. Drive to your authorized Audi
dealer or qualified repair facility immediately
to have the problem corrected. On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary.
Low brake fluid level
When the brake fluid level is low, malfunc­
tions in the brake system may occur. The brake fluid level is electronically monitored .
Brake booster
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A WARNING
-- You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by resting your foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes

can reach the catalytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Placing your vehicle
out of service.
I f you wou ld like to take your vehicle out of
service for a longer t ime, contact your aut hor­
iz ed A udi dealer or qualified repair facility .
They will advise you o f important meas ures,
such as cor rosion protection, maintenance
and storage procedures. Also follow the infor ­
mat ion about the battery¢

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle , as well as ex­
haust and noise levels.
F ue l economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors:
Dri ving and the en vironm ent 195
-your personal d riving s tyle
- operati ng conditions
- technical limitat io ns
If you ant ic ipate what you need to do next and
drive econom ically , yo u can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
(D Tips
The consumption estimates as published
by ENVIRO NM EN TAL PROT ECTI ON AG ENC Y
( E PA) and Transpo rt Canada may no t cor re­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id u nnecessary accelerating and brak ing.
Vehicles use the mos t fu e l when they are ac­
ce lerating. If you anticipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce le rat ing gently re duces fue l cons ump ­
tion, eng ine wear, and does not disturb the
environment .
Fuel consumpt ion, exhaust em iss ions an d en­
gine noise inc rease disproportionate ly at high
speeds . If you drive at approximately three
quarte rs of top speed, fuel consumption wi ll
be reduced by one ha lf. Never drive faster

ditions permit.
Reducing unnecessary idling
Even wh en your car is just idling it burns up
fuel.
,.. Shu t the engine off when you a re not dr iv ing
the vehi cle.
... Do not warm up the vehicle by letting the
engine run at idle.
It is efficien t to switch off the engine when
stopped at railroad crossings and long red
lights. Turning the engine
off for j ust 30-40
seconds saves mo re f uel than is burned by
start ing the engine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid ru nning at h igh rpms while the engine is
still warming up.
{[) Note
Do not leave engine idling unattended af­
ter starting. If warning lights s hould come
on to indicate improper operation, they
wou ld go unheeded . E xtended idling also
produces heat, which cou ld resu lt in over­
heat ing or o ther da mage to the vehicle or
o ther prope rty.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serv iced at regular inter-
vals.
H aving your vehicle regular ly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . T he condition
of yo ur vehicle not only affects its safety and
ab ility to hold its value, it also affec ts
fuel
con sumption. Check
your oil each t ime you fill your tank.
T he amou nt of oi l used is re lated to engine
lo ad a nd speed.
It is normal fo r the oil consumption of a new
engine to reach its lowest valu e after a c erta in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt io n.
This also app lies to fue l consumption and en­
gine output .

smoothly and reliably. Choosing the right oil
and changing oil within the time and mileage intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a special quality standard for engine oil that
will help assure that your vehicle's engine will get the lubrication it needs for proper opera­
tion .
Modern engine lubrication has taken a quan ­
tum leap in the last few years. Many synthetic
oils available today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils , making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­ based engine oil , the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine
running smoothly and help prevent the for­
mation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive
repairs .
At the time of printing, engine oils available in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every synthetic engine oil will
meet Audi oil standard VW 502 00 . So always
be sure that you use an approved oil.
To help prevent the formation of harmful de­ posi ts use only oil with the following specifi­
cations printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion singly or in combination with other desig­
nations and oil quality standards.
Viscosity
Engine oils are graded according to their vis­
cosity . The proper viscosity grade oil for your
engine depends on climactic or seasonal con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across all tem­
perature ranges for normal driving conditions.
Checking and Filling 213
However, if engine oil viscosity grade SAE
5W40 is not available , you can also use viscos­
ity grade SAE 5W -30 or SAE OW-40 as long as
it meets Audi oil quality standard VW 502 00
specifications.
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart
(liter) of oil that expressly conforms to the
VW 502 00 spec ificat ion, in case you have to
top off the oil while on the road .
Only if the level of the oil is at or below the
minimum mark -and no oil that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top off
with a high quality engine oil , preferably syn ­
thetic-based, that meets ACEA A3 or API SM specifications, but even then, only in viscosity
grades SAE 5W-40 , SAE SW-30, or SAE
OW-40. However, during the entire time be­
tween oil change intervals, never top off with
more than a total of 0.5 qt/liter engine oil
that does not conform to Audi oil specification
vw 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822 -2834
or v isit our web site at www.audiusa .com or
www .audicanada .ca. Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your veh icle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter-
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when .,..

214 Checking and Filling
you have your oil changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods .
Detergent additives in the o il wi ll make fresh
oil look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00. Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dea ler will have to
deny warranty coverage un less yo u present to
the dea ler proof in the form of Service or Re­
pair Orders that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports.
In order to provide effective lubrication and
cooling of internal engine components , a ll in­
ternal combustion eng ines consume a certain
amount of o il. Oil consumption var ies from
engine to engine and may change significantly
over the life of the eng ine . Typically, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
b reak-in period than they consume after oil
consumption has stabilized. Under
normal conditions, the rate o f oil con ­
s u mption depends on the quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
co nd ensat ion or fuel residue and the oxida­
t ion level of the oil. As any engine is subject to
wea r as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard ra te of oil consumpt io n can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the oil lev­
el , see
Note.
If the yellow engine oil leve l warning symbo l
Ill in the instr ument cl uster light s up, you
shou ld check the oil leve l as soon as possible

(D Note
Driving wit h an insufficient oil level is like­
l y to cause severe damage to the engine.
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­
erably each time you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Audi ..,.
